Description: 3Com CoreBuilder 9000 MIB for managing packet module backplane interfaces, link connections, and fabric cards in the CB9000 modular chassis

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CB9000-PACKET-MODULE-MIB?

This is a 3Com-specific MIB for the CoreBuilder 9000, a modular high-end enterprise chassis switch/hub, covering the packet module component that handles backplane interconnects and fabric switching. It exposes configuration and status data about backplane interface connections, slot-to-card mappings, and general card inventory/type information within the chassis. Its main hardware-monitoring value is tracking chassis slot and card population—confirming which card type occupies each slot, whether backplane connections between modules are correctly established, and detecting missing or misconfigured cards—rather than fine-grained temperature or power telemetry. It is a standalone 3Com enterprise MIB with no apparent dependency on other standard MIBs beyond base SNMPv2 conventions. It would have been deployed in large enterprise data centers or campus core networks running 3Com CoreBuilder 9000 chassis switches. Engineers can download the CB9000-PACKET-MODULE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CB9000-PACKET-MODULE-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An operator would walk cb9000GenCardTable (keyed by cb9000GenCardIndex and cb9000GenCardLocationIndex) to inventory which cb9000GenCardType is installed in each chassis slot and detect if a card has been removed or replaced unexpectedly. The cb9000BackplaneConnectTable, indexed by cb9000BackplaneConnectIndex, cb9000BackplaneConnectIfIndex, and cb9000BackplaneConnectSlotIndex, lets an admin verify that a given interface's backplane path to its fabric/slot connection is intact, flagging a fault if cb9000BackplaneConnectTraceIndex shows an unexpected or broken trace. cb9000BackplaneInterfaceCount gives a quick sanity check on total backplane interfaces present versus expected.

What Can Be Monitored

installed card types per slot
backplane interface count
backplane connection/trace status
slot-to-card mapping
